3D Mammography

3D imaging of the same area

different angles provides
additional detail.

What is a 3D mammography breast exam?

3D mammography is a new diagnostic tool that is used together with
traditional 2D imaging to build a finely detailed 3D reconstruction of
breast tissue. Radiology physicians can then scroll through all the
images much like a book - one page at a time - to gain a better
understanding of your breast health.

What are the benefits of 3D mammography?

Sometimes breast tissue can overlap, which when viewed only with
conventional 2D mammography, may look like an abnormal area. Examining
multiple images with 2D and 3D techniques allows the radiologist to
view tissue more clearly, making it easier to make an accurate
assessment and less likely that you will be asked to return for
additional views. Abnormalities may be easier to see and evaluate,
making it possible to identify cancers at earlier stages when they are
most treatable.

Is 3D mammography used for screening and for diagnostic exams?

A screening mammogram is a routine evaluation of the breast. A
diagnostic mammogram focuses on an area of the breast that is unclear
or is used to evaluate a symptom or complaint. Conventional 2D and the
new 3D mammography may be used together to screen or to diagnose a
breast issue.

What should I expect during the 3D mammography exam?

Traditional 2D and 3D mammography are performed on similar equipment.
No additional compression or positioning is required during the 3D
exam, and it only takes a few seconds longer than the 2D exam for each
view.

During the 3D image acquisition, the X-ray arm will move in an arc over
the breast, taking multiple images over the course of a few seconds.
The technologist will view the images to ensure they are of the highest
quality. The radiology physician will then study the images and dictate
the findings in a report to send to your doctor. Your doctor will
discuss the results with you.

Is there additional radiation exposure with 3D mammography?

With the more advanced, lower dose C-ViewTM software, the radiation used
for the 2D together with the 3D exam is now about the same as with a
traditional 2D mammogram alone.

Are there additional costs?

Some insurance companies do not yet cover 3D mammograms, but
legislation and coverage are always changing. Please check with your
insurance provider to understand your health care policy. There may be
an additional out-of-pocket charge to you.
